Two in one: the official Construction Master® Pro from Calculated Industries for your iPhone and iPad includes two models: #4065 and #4080 (CM Pro with Trig). And while perhaps obvious, if you change from an iOS device to a non-iOS device, you WILL need to buy a new license as they are incompatible.

Advanced Feet-Inch-Fraction Construction-Math Calculator by Calculated Industries, built with the same features and functions, and with the same core engine that powers the industry-standard advanced construction-math calculators from Calculated Industries. You’ll actually get two apps in one, since the Construction Master Pro for iPhone has all the functionality of the Construction Master Pro and the Construction Master Pro Trig -– and includes a full User’s Guide built in, as well as the ability to press and hold a key for specific help!

I work with dirt doing estimates and such finally this app came out its the same as my calculator i keep in my truck

The Best In Construction Calculators!

I paid a lot more for the physical calculator years ago & what an asset it is. The app is identical & incredibly useful in the world of construction. I would reccomend this app for anyone!

Worth the price excellent app

I own the physical calculator of the same type and paid $80 for it, the addition of the iPhone version that I always have on me is more than worth the additional cost. They have been an industry leader with their calculators and the addition of the IPhone app is a welcomed one

worth it

works great im a journeyman carpenter never go anywhere without my ipod its 1 less thing to carry and a fraction of the price of a seperate unit


The best app I have! All the same features of the stand alone calculator for a quarter the price! Nice to always have access to the help too.

Construction master

Just as good as my old construction master that I have had for years, and payed $130 for. This app is worth every penny.


This is an excellent addition to any toolbox worth every penny. The help button is fantastic.
